In the new book Mad for It Andy Mitten talks to managers, players, backroom staff, local journalists and to a host of passionate fans to illuminate the conflicts, tensions, histories and culture behind these fascinating games. From the biggest global clashes and little known derbies in Cairo or Calcutta which attract twice as many fans as any Old Firm clash, to the coldest derby in the world, and the friendliest - Mad for It journeys across the UK and to the far-flung regions of planet football to discover the classic derby matches.
